The authors conclude that plant-based, vegan meals may be a “more effective tool” to prevent type 2 diabetes (T2D) than meat-based meals. They say that they’ve used a “randomized crossover design”. And that they’ve compared effects of two different meals on gastrointestinal hormones, and satiety (feeling of fullness) on healthy, obese and diabetic men.

The meals: a processed-meat and cheese meal and a vegan meal with tofu.

US psychiatrist Dr Georgia Ede calls the study misleading. Whoever designed it “has some explaining to do”, she says. US physician Dr Tro Kalayjian is more forthright and calls it: “biased bullshit”.
